CIRCUIT DESCRIPTION
2. Outline of MovementsBelow are description on of the outline of movements of HW during DVD video and CD playback.
2-1 Movements during DVD video playback
1) The DVD mechanism transfers data read from the DVD video disk to the MPEG decoder via the AV
interface.
2) The MPEG decoder, conducts analyses of the received data at the Pre Parser (Write FIFO). Then, the
decoder divides up the data into video data, audio data, sub-picture data, navigation pack and system
data, and then stores the data in SDRAM.

3) The CPU watches over the data stored in SDRAM (System Channel Buffer, Navi Pack Channel Buffer)
and when data with designated length is stored, instructs MPEG decoder to start decoding.
4) When instructed t o begin decoding on the data, the MPEG decoder reads the data stored in SDRAM and
transfers the data to decoder modules, as shown in the diagram below.

5) Data forwarded to the Video Decoder Module and SPU Decoder Module is decoded and then forwarded
to the Video Interface Block, as shown in the diagram below(fig.4).

L64021
Data forwarded to the Video Interface Block is converted to 8-bit pixel data (ITU-R BT.601) either in
NTSC or PAL format (set by register). Then the data is synchronized with the H-Sync/V-Sync signal output
by the 27MHz clock and Video Ehcoder (ADV7170) and forwarded to the Video Encoder.

The data forwarded to the Audio Decoder Module is decoded by the format designated by the user, or
with the format recorded in the DVD video disk (Linear PCM, Dolby Digital, MPEG). At the same time, it is
SPDIF output using the same format as the decoded audio format. (DTS cannot be decoded and only
SPFIF output is possible.
The decoded data is synchronized to Audio CLK (384fs) after converting to audio data (SDAT,
LRCLK, BCLK) and hen forwarded to the Audio DAC (AK4353).

CIRCUIT DESCRIPTION
6) The pixel data forwarded to the Video Encoder is converted to composite and RGB signals of NTSO or
PAL formalt and transmitted to the liquid crystal panel and image output circuit.
The audio data (SDATA, LRCLK, BCLK, Audio CLK) forwarded to Audio DAC is converted to 2-
channel L-R signal and output form RCA connector.
2-2 Movements at the time of Replaying CD
1) The DVD mechanism forwards the data read from the CD to MPEG Decoder via the CD-DA interface.
2) In CD mode, the MPEG Decorder will be in the bypass mode and forwards the input data to Audio DAC
without doing any thing to it.
3) The Audio data (SDATA, LRCLK, BCLK, Audio CLK) forwarded to the Audio DAC is converted to 2-
channel L-R signal and output from the RCA connector.
At the same time, the input audio data is converted to SPDIF by the DIT (Digital Interface Transmitter),
which is built into Audio DAC, and is output to MPEG Decoder.
The SPDIF data input by the MPEG Decoder is, again, output from the MPEG Decoder at the same
time as playbacking of the DVD, without being worked on.
2-3 CPU peripheral circuit movement
The CPU conducts control over the DVD Video System as a whole. The program is stored in the flash
memory and the DRAM is used as the program work area. The CPU mainly controls the LSI control such
as MPEG Decoder, Video Encoder, Audio DAC, etc, and the like and also controls communication with
the Host CPU, and DVD Mechanism.
In communication with the Host CPU, simple serial communication is used and communications on
system control commands and DVD and CD related communications such as Playback Control (Remote
Control Code) are conducted.
The communication with DVD mechanisms is conduced by using local interface mainly for disc
information and analysis of playback information instructed by the host CPU on DVD and CD, and for the
communication of DVD mechanism control information.
